An expandable array and methods of maintaining a biological sample within an expandable array are provided. The expandable array includes a plurality of receptacles configured to receive a biological sample and a plurality of beams comprising a programmable material. Each beam of the plurality of beams is located between and connects at least two receptacles. The programmable material can be a shape-memory polymer or a magnetoactive material that transitions the plurality of beams from an extended state to a contracted state upon application of a stimulus.

An all-in-one self test kit includes: a test tool having a reagent container adapted to store a diagnosis reagent therein and a diagnosis kit with a casing constituted of a first body and a second body and a diagnosis strip disposed inside the casing and having a sucking part for sucking the diagnosis reagent and a diagnosis part reacting to the diagnosis reagent sucked to the sucking part; a sub-body having a container insertion portion for inserting the reagent container thereinto and a kit insertion portion for inserting the diagnosis kit thereinto; a main body for inserting the sub-body thereinto; and a cap fastened and unfastened with an entrance of the main body to open and close the main body.

A method for preparing for preparing a solution comprising a plurality of particles in a vial is disclosed. The method includes agitating the vial at a first predetermined mixing speed. The method also includes dispersing, into the vial, during the agitating, a first volume of buffer solution at a first predetermined dispensing rate to suspend the plurality of particles in the solution, wherein particles of the plurality of particles comprise a unique identifying feature.

The present disclosure provides systems and methods for intracellular delivery. The systems and methods may comprise the use of a cell processing apparatus which may comprise a plurality of compression elements such as ridges. The intracellular delivery may be caused by rapid compression of cells, which may result in a reduction of a cell volume. The compression may occur while the cells pass through gaps formed by at least a subset of the ridges. The cell processing apparatus may further comprise one or more recovery spaces which are positioned between adjacent ridges. The cells may recover at least a portion of the reduced cell volume by absorbing media and/or reagents surrounding the cells while flowing through the recovery spaces. The ridges may also divert less compressible cells into a diversion channel, thereby sorting the cells based on various cell properties and/or preventing clogging within the apparatus.

Disclosed is a sensor assembly 100 including a sensor body having a flow channel therein configured to receive a test liquid, such as a bio-liquid, one or more moveable walls defining one or more wall portions of the flow channel, the one or more moveable walls configured to be moveable, such as to a first position, a second position, or even an intermediate position, to change a volume of the flow channel 102, and one or more sensor elements positioned in the flow channel. Volume in the flow channel may be minimized for testing neonatal specimens. Liquid testing apparatus and methods of testing test liquids are provided, as are other aspects.

A door for a laboratory workstation is disclosed. The laboratory workstation has a horizontally extending work surface for providing a working area. The door is movable in relation to the work surface in a vertical direction perpendicular to the work surface between a safety position, in which the door closes the working area for manual access of a user, an access position in which the working area is open for manual access of a user, and a loading position.

The present invention relates to an apparatus for nucleic acid amplification and, more particularly, to an apparatus for nucleic acid amplification capable of rapid nucleic acid amplification by rapidly heating and cooling a reactant in a reaction vessel for a chemical/biochemical reaction requiring a temperature change, and a method for temperature control in nucleic acid amplification.

One aspect of the present invention provides a nucleic acid amplification device. The device may include a plurality of heating blocks disposed to be spaced apart; a polymerase chain reaction (PCR) chip including an inlet portion into which a solution sample is injected, a reaction chamber in which PCR of the solution sample is performed, and an outlet portion through the solution sample is discharged, the PCR chip coming into sequential contact with the plurality of heating blocks, in which the PCR of the solution sample is performed; a chip holder on which the PCR chip is mounted and which moves the PCR chip to allow the PCR chip to come into sequential contact with the plurality of heating blocks; and a driving portion configured to move the chip holder and to guide a movement direction of the chip holder.

A multichannel pipetting head comprises a plunger actuator comprising at least one groove with an upper border, and a lower border. A plurality of plunger-cylinder units, wherein each plunger-cylinder unit comprises a cylinder and a plunger comprising a plunger head. The plunger head comprises a projecting upper abutment region adjoining the upper border, a projecting lower abutment region adjoining the lower border and laterally offset relative to the projecting upper abutment region, a plurality of guides. Each of the cylinders is coupled to a neck and held on each of the plurality of guides. During lateral movement of the plurality of guides, the plunger head is configured to tilt in the groove and to be held with the upper abutment region abutting the upper border and with the lower abutment region abutting the lower border of the groove due to restoring forces that occur during tilting in the plunger-cylinder units.
